Strength of hot rolled sections and plates perpendicular to direction of rolling

[bugbus]

Is there any significant difference in the yield or tensile strength of hot rolled steel in the directions parallel and perpendicular to rolling?

Do any of the codes make any distinction here?

Thanks

I'm not aware of any differences in any of the codes I'm more familiar with in terms of tensile or yield stress.

I'm aware there is a different limit on cold bending plate to a radius depending on the direction of rolling (in addition to the plate thickness). That's the only 'directional' effect I'm aware of based on my experience.

In the meantime I have done a bit of my own research on this topic. The results seem to show that there is not much difference in strength for the two directions, perhaps slightly greater in the transverse direction, which surprises me.

“In hot rolled steels, the yield stress and tensile strength are generally higher in the transverse direction than in the rolling direction and often show a minimum at ∼30° to the rolling direction.”

Yield and tensile strength are somewhat greater in the transverse direction to rolling.

No significant difference

The title of this post , ( Strength of hot rolled sections and plates perpendicular to direction of rolling )

In case of plate , if the plate is loaded in tension perpendicular to its plane, that is , parallel to the thickness direction, the there is a risk for the lamellar tearing if the material does not have adequate through-thickness properties.

I will suggest you to look lamination and lamellar tearing .
